Codiga

Codiga embeds a static analysis engine directly into IDE environments (VS Code, JetBrains, etc.) that performs incremental AST-based parsing and pattern matching on code as it's typed, surfacing violations and quality issues with sub-second latency. The system uses AI to generate contextual rule suggestions based on detected anti-patterns, reducing manual rule configuration. Analysis results are streamed to the editor as inline diagnostics without requiring full file saves or CI/CD pipeline execution.

Codiga implements a language-agnostic rule evaluation framework that parses source code into Abstract Syntax Trees (ASTs) for Python, JavaScript, TypeScript, Java, and Go, then applies pattern-matching rules against these trees to detect violations. Rules are defined as declarative patterns (likely YAML or JSON-based) that specify AST node types, attributes, and relationships to match. The engine supports both built-in rules and user-defined custom rules, with rules organized by category (security, performance, style, best-practices).

Codiga integrates into CI/CD systems (GitHub Actions, GitLab CI, Jenkins, etc.) as a build step that runs static analysis on pull requests or commits, blocking merges if quality thresholds are violated. The integration uses webhook-based triggers to initiate analysis on code push events, aggregates results into a pass/fail gate, and posts inline comments on pull requests with violation details. Results are persisted and compared against baseline metrics to track quality trends over time.

Codiga uses machine learning models trained on code patterns and violations to automatically suggest relevant rules based on detected anti-patterns in a codebase. When the analyzer encounters repeated violations or suspicious patterns, the AI backend generates rule recommendations with explanations and severity levels. These suggestions are surfaced in the IDE and CI/CD reports, allowing developers to adopt rules with a single click rather than manually configuring them.

Codiga implements incremental analysis that tracks code changes (diffs) and re-analyzes only modified files and their dependents, rather than scanning the entire codebase on every check. The system maintains a baseline of previous analysis results and compares new results against this baseline to identify new violations, fixed violations, and unchanged issues. This approach reduces analysis time from minutes (full scan) to seconds (incremental scan) for large codebases.

Codiga includes a security-focused rule set that detects common vulnerabilities (SQL injection, XSS, insecure deserialization, hardcoded secrets, etc.) and maps findings to OWASP Top 10 and CWE (Common Weakness Enumeration) standards. The detection engine uses pattern matching on ASTs to identify dangerous function calls, unsafe data flows, and insecure configurations. Security violations are prioritized with severity levels (critical, high, medium, low) and include remediation guidance.

Codiga collects and aggregates code quality metrics (violation count, severity distribution, rule coverage, code duplication, complexity scores) across commits and time periods, storing historical data to enable trend analysis. The system generates dashboards and reports showing quality metrics over time, allowing teams to track improvements or regressions. Metrics are broken down by file, module, rule category, and severity level for granular visibility.

Codiga provides IDE extensions (VS Code, JetBrains IDEs) that display code quality violations as inline diagnostics (squiggly underlines, gutter icons) and offer quick-fix suggestions via IDE code actions. When a violation is detected, the extension highlights the problematic code, displays the rule name and explanation, and provides one-click fixes where applicable (e.g., auto-formatting, removing unused variables). The extension integrates with native IDE features (problems panel, breadcrumbs, hover tooltips) for seamless user experience.

Codiga offers a free tier that includes basic static analysis with built-in rules, IDE extension access, and limited CI/CD integration (e.g., 1-2 runs per day or 100 analyses per month). The free tier includes access to a community rule library (though limited compared to paid tiers) and basic metrics tracking. Paid tiers unlock unlimited analysis runs, advanced rules, team collaboration features, and priority support.
